Will give hi there, this lesson is way overdue and i really need to get it done. can someone me figure them out? 1. find the slope of the line that passes through (-2,-3) and (1,1). a) 1/3 b) 1 c) 2 d) 4/3 2. a line with slope = 1/2 passes through the points (2,5) and (x,3). what is the value of x? a) -1 b) 1 c) -2 d) 2 3. for the equation -4y =8x, what is the constant of variation? a) -4 b) -2 c) 1 d) 2

1. is D) 4/3    To find the slope we will insert the numbers into this formula: y2 - y2 / x2 - x1, so... 1 + 3/ 1 + 2 (the negatives canceled each other out)

now simplify and it becomes 4/3

so ur answer to 1. is D) 4/3

2. Plot this one...it rly helps...then use the slope to find the point ur looking 4, the answer is C) -2

3. The answer is B) -2

Hope that helps u out!! :)

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer
